of dealing with genera cannot be adopted, and as yet we do not know 
whether the two species are so much alike as to be placed together.

grown); sculpture longitudinal striz, regular and broadly ridged, 
also showing as spiral striz on the base ; colour olivaceous brown; 
spire quite depressed, apex flat; suture very shallow; whorls 4, 
sides flat above, rounded on periphery; aperture lunate, moderately 
large, nearly vertical; peristome thin, oblique below, a good deal

A small specimen of 23 whorls sent back to me by Mr. Nevill out 
of a series of Dafla shells given by me to the Calcutta Museum is, 
no doubt, the young of this species, the apex and spiral curve and 
sculpture being exactly similar. A number of these minute Helices 
will, I think, turn out to be young shells,
